Subject: -G to smaller doesn't move superblock... is there _any_ way to shrink?
Date: Fri, 6 Nov 2009 07:53:34 -0500	[thread overview]
Message-ID: <20091106125334.GC6212@Toms.NET> (raw)


So, I thought the logical sequence was:

	resize2fs <smaller>
	mdadm -G -z <smaller>
	fdisk <smaller>

... but ...

the mdadm -G -z <smaller> seems to leave the superblock at the end of the partition...

Is there _any_ way to do what I'm trying to do?  I don't see options to tell it I want
the superblock to be at offset X or that the partition is "going to be" smaller... and
I don't see options for switching the superblock format and moving stuff around... and
I'm really not wanting to do --create and cross my fingers that everything "just works".
